Version 2.2 is compatible with Mac OS® X Yosemite (10.10). The Theory of Plate Tectonics is a dynamic exploration of
how Earth's lithospheric plates change through time. Version 2.2, fully
narrated, embarks on a new way to study this exciting theory. All artwork
enhances the understanding of the topics covered including many
animations, which are easily manipulated by the user. Included is an
illustrated glossary with audio pronunciations. An index makes it easy
to jump to selected frames covering a specific geologic term. Navigation
throughout the program is easier with fast forward, fast reverse, jump to
a numbered frame, glossary, and index buttons available on every frame.
